I don't think so. I think that hang was a hard one. If it happens with a
kernel built by me that you got off my site, then it's not. If you're running
on a distro that has a "kgcc", then build with that and see if the problem
goes away.

Just to fill everyone in on what happened with this - I looked at this with
Bill today and it turns out to be a compiler problem.
At -O2, the default gcc on whatever distro Bill was running calculates
addresses of labels incorrectly. Switching to kgcc fixed the problem.

It happens every time with the linux-2.4.0-test9 and linux-2.4.0-test10
kernel binaries I downloaded from your site. I'm running on Slackware
7.0, kernel version 2.2.16.
I don't mind it so much since it goes away after I install Slackware,
but I was curious as to what causes it.

When I run UML for the first time (to install Slackware), it hangs
during the boot process after:
none on /proc type proc (rw)
If I press CTRL+C, UML boots up fine. Once I've installed Slackware, I
don't have this problem anymore. Any idea what this is, or if it's
related to the problem Bill was having?
